The High Holidays, Rosh Hashanah and Yom Kippur, are, as their designation implies, two of the holiest days of the Jewish year, and as such are classically celebrated with music. The melodies are not light hearted or joyful. These are the Days of Atonement when Jews the world over confess their wrongdoings as individuals and as a community, and commit themselves to do better in the future. For Rosh Hashanah, the chosen music includes the Kaddish or prayer for the dead, the Aleinu, Areshet S'Fateinu and Shirat Ahavah. Yom Kippur begins at sundown with the mournful Kol Nidre and continues with beloved melodies such as Sh'ma Koleinu.
